UTF-16 Encoding

As shown in Table B-1, UTF-16 character codes for some characters (Additional Chinese/Japanese/Korean characters and Private Use Area #2) are represented in two units of 16-bits. These are the surrogate pairs. A surrogate pair consists of two 16-bit values. The first 16-bit value is the high surrogate (the values are from 0xD800 to 0xDBFF). The second 16-bit value is the low surrogate (the values are from 0xDC00 to 0xDFFF). With surrogate pairs, UTF-16 character codes can represent more than one million characters. Without surrogate pairs, only up to 65,536 characters could be represented. Oracle's AL16UTF16 character set supports surrogate pairs.
